Nah, unless devs mentioned something about this recently, idealized gear is one and done, wont be tied to anyhthing else and doubt we'll see another way to get. The Ex fight isnt really that hard to be honest, its just mechanics, dps check give you a ton.... of time to down them, we'll prolly see the usual echo and maybe a tweak to the idol and rewards, thats about it. If we see a gear set from Bozja it'll be completely new role based set.
